Ski

A ski adapted to support a user's boot, said ski comprising:

• a front tip;
• a rear end;
• a central zone positioned between the front tip and the rear end;
• the central zone, when positioned on a planar surface, forms at least two contact lines with said planar surface, said at least two contact lines comprising:
• a front contact line positioned closer to the front tip than to the rear end;
• a rear contact line positioned closer to the rear end than to the front tip;
• a distance separating the front contact line from the front tip being greater than 500 millimeters;
• a shovel extending from the front contact line to the front tip, said shovel having a convex zone comprising:
• a first shovel portion having a lateral profile having a shape of a circular arc, said circular arc having a radius with a length between 5 meters and 9 meters;
• a second shovel portion contiguous to said first shovel portion, said second shovel portion having a shape of a circular arc, said circular arc of said second shovel portion having a radius with a length between 1 meter and 9 meters;
• a third shovel portion contiguous to said second shovel portion and extending to the front tip of the ski.

A ski comprising:

• a front tip;
• a rear end;
• a front contact line;
• a rear contact line;
• the ski contacting a planar surface when supported on the planar surface at the front contact line and the rear contact line, while each of said front tip and said rear tip is spaced above said planar surface;
• from the front tip to the rear end, the ski having a length L defined by:
• a shovel having a length DS extending from the front tip to the front contact line;
• a central zone extending from the front contact line to the rear contact line;
• a tail extending from the rear contact line to the rear end;
• a ratio DS/L within a range between approximately 0.26 and approximately 0.38.

A ski comprising:

• a front tip;
• a rear end;
• a front contact line;
• a rear contact line;
• the ski contacting a planar surface when supported in a non-stressed state on the planar surface at the front contact line and the rear contact line, while each of said front tip and said rear tip is spaced above said planar surface;
• from the front tip to the rear end, the ski having a length L defined by:
• a shovel having a length DS extending from the front tip to the front contact line, said length being greater than 500 millimeters;
• a central zone extending from the front contact line to the rear contact line;
• a tail extending from the rear contact line to the rear end;
• a ratio DS/L within a range between approximately 0.26 and approximately 0.38;
• in a non-stressed state of the ski, the shovel comprises:
• a first shovel portion having a lateral profile with a radius of curvature between 5 and 9 meters and extending through a point of the front contact line and tangent to a lateral profile of said central portion;
• a second shovel portion contiguous to said first shovel portion, said second shovel portion having a lateral profile with a radius of curvature between 1 and 9 meters and extending through a forward end point of the lateral profile of the first shovel portion and tangent to the lateral profile of said first shovel portion.

• a rear end;
• a central portion positioned between the front tip and the rear end;
• the central portion, when positioned on a planar surface, forms at least two contact lines with said planar surface, said at least two contact lines comprising:
• a front contact line positioned closer to the front tip than to the rear end;
• a rear contact line positioned closer to the rear end than to the front tip;
• a distance separating the front contact line from the front tip being greater than 500 millimeters;
• a bottom edge structured and arranged to come into gripping engagement with snow during edging of the ski in a turn, said bottom edge comprising a running edge extending between the front and rear contact lines;
• means for increasing a length of edge-gripping snow engagement as soon as the turn is initiated to be greater than the length of the running edge between the front and rear contact lines, said means comprising:
• lines of maximum width of the ski comprising a front line forward of the front contact line and a rear line rearward of the rear contact line;
• a shovel extending from the front contact line to the front tip, said shovel comprising
• a first shovel portion having a lateral profile between a first pair of circular arcs, said first pair of circular arcs being a first circular arc having a radius of 5 meters and a second circular arc having a radius of 9 meters, each of said first pair of circular arcs extending through a point of the front contact line and tangent to a lateral profile of said central portion;
• a second shovel portion contiguous to said first shovel portion, said second shovel portion having a lateral profile between a second pair of circular arcs, said second pair of circular arcs being a first circular arc having a radius of 1 meter and a second circular arc having a radius of 9 meters, each of said second pair of circular arcs extending through a forward end point of the lateral profile of the first shovel portion and tangent to the lateral profile of said first shovel portion.
